Firstly, one could describe the product by giving it the title "VFM".
The packaging I purchased includes everything mentioned in the description. It allows you to charge mobile phones, computers, and personally, I even used it to charge an electric scooter.
The car, a WV Passat 1.4 model 2010, had been immobilized for 8 months and even the electric lock was not working. While the previous starter, worth 90€, required activating the Extra Booster to provide voltage in a similar situation, this one did it instantly with a simple process.
Instructions for first-time users:
1) As soon as you open the box, you will find a wall charger and you will connect it to make a full charge. Throughout the charging process, the starter should be turned off in the OFF position.
2) After the charging is complete and you go to the car, you will first connect ONLY the clamps to the corresponding positions of the battery. The red clamp to the + and the black clamp to the -.
Then, you will connect the double contact to the starter by opening the lid next to the point that says ON-OFF.
Once you have completed the steps, you will activate the starter by turning it towards the ON position. You will see the indicator light on, and then you can enter the car to start it.
3) After providing the appropriate voltage and starting the car, you turn the starter to the OFF position, remove the cable from the device, and finally remove the clamps carefully.
If it is nighttime and you need a flashlight, press the central button for 2 seconds and the flashlight will turn on. To turn it off, continuously press the button until it closes.
To charge a computer or an electric scooter, plug in the corresponding connectors, check the voltage displayed on the respective device, and hold the central button for more than 3 seconds to switch the selection to the desired voltage.
